Hi Gang - Finally put an exhaust on my car!! Its is an all mandrel system. The downpipe is 3" and then it transitions up to 3.5", from which point it is 3.5" all the way to the tip. It took just over 8hours to fab and was done by one of the skilled fabricators here in town. He was able to take the 3.5" over the axle so there is lots of ground clearance and its nicely tucked as well.
The Downpipe came out great and has three bungs for the 02, data logging and a spare gauge.
The muffler is from Burns and, it is 3.5" in diameter as well and 16" long and weighs only a hair over 3lbs (!!), the coolest Mufflers I have ever bought. It can be re-packed and rebuilt.
The tip is from Magnaflow.
Car sounds angry but not overbearing, has a great rumble to it.
